Pre Sintered Preforms - PSP Preforms

PSP™ is a customized blend of superalloy and braze powders in either a plate form or specific shape allows selective build-up of worn surfaces to be achieved quickly and efficiently offering savings in time and cost. The porosity of custom performs is less than 2%, so little or no shrinkage occurs–this is a major advantage of MTC Wesgo Metals' PSPs™ over traditional brazing pastes and green tapes.
